  Fig. 1. Treatment protocol (patient no. 1). (A) Procedure image before treatment showing a benign recalcitrant stricture at an esophago-colonic anastomotic site. (B) Procedure image showing liquid nitrogen application in the freezing phase. (C) Procedure image after the thawing phase showing dilation with a 4 cm controlled radial expansion balloon. (D) Procedure image post-dilation showing the treatment effect with improved patency of the stenotic site.
